i used this cd 5 times no problem. the last two times it was bad. i cleaned the cd so that is not it. the only thing i can think of is somewhere during the install i got the option for updates during install. plus one i think for a cd player mp3 . i said yes to the cd mp3 install the last two times. it is a problem to download from the softwarecentrum. it is slow or stops. the normal internet is good. i hope this is useful ubuntu 14.04 lts greetings ferry
